Wall clouds were reported across the Kansas City metro Wednesday night, including some reports of rotation and even brief touch downs in eastern Jackson County and Cass County.

Trained spotters and residents reported a tornado in Lee's Summit and one in Pleasant Hill. There were reports of some damage, and as of 8:11 p.m., more than 10,000 Kansas City Power & Light customers were without power.

"I looked up over my windshield. There was rotation. The rain bands were spinning around me," said storm chaser Zach Kurth, who caught up with the storm near Lee's Summit North High School.

The tornado knocked down a PTA fireworks tent in the school parking lot.

Jeanne Nixon says she and the other volunteers piled into a car and left just minutes before the tornado hit.

“We came back up here and found dozens of fire trucks and fire personnel,” said Nixon. “They were actually looking for us because they thought we were still in because of all the cars the parked here."

The system was rain-wrapped, making it hard for meteorologists to see rotation, even from helicopters.

A tornado warning was issued for Jackson, Cass and Johnson counties in Missouri.
